I CEQ.

, BUNG-BUSHIN-G COOLER.

To all whom it mayconccrn:

, Be it known that I, THEODORE B. Sonimrrr, a citizen of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have in vented certain new and useful Improvements in Bung-Bushing Coolers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. i

' This invention relates to coolers for bushings for bung holes, and particularly to means that may be inserted and removed at will from a bung hole.

An object in view is the provision of a hol- 7 low housing adapted to fit a bung hole and arranged to] accommodate the passage of water through the same, in order to present a cool surface to the bung hole or aroundthe bung hole. I q i s A further object in viewis the provision of means forpreventing the heating and expansion of bung hole bushings when the receptacle to which the sameis secured is heated, the means comprising a hollow housing with a passageway therethrough for permitting the removal of the contents of the receptacle, andthe hollow part of the housing accommodatmg ,a' cooling agent, whereby the bung bushing maybe keptoool and yet the contents of'the receptacle readily removed. With these and other objects in view, the invention consists in certain novel constructions, combinations, and arrangements of parts as hereinafterfully described and set forth in the appended'claims.

Fig. 1 approximately on line In the use of receptacles such as kegs and instance, ale and beer, it is found very desirable and almost absolutelynecessary to coat the inner surface of the receptacle, such as a keg, with pitch or some other substance that has substantially the same functions. After the keghas been used for some time, it is found necessary to, renew the coating I and, in order to do so, thekeg must be heated to a suihcientsdegree to melt the pitch, for

leaks around the bung bushingby reason of the fact that the bushing has contracted after cooling and the keg remained in its eX- panded condition as it is forced by the eX- pansion of the bushing.

In order to properly re-pitch kegs and the like without causing any leakage between the bushing and the bung hole, I have arranged a cooling device that is adapted to fit into the bushing snugly and which permits the removal and insertion of pitch through a central aperture, as well as permitting the insertion of steam or other heating medium. This cooling device is construoted with a housing and is arranged with. a hollowed out central portion having extending therethrough passageways which permit the insertion of the cooling medium into the hollowed out portion, and the removal thereof. A removable cylindrical tube or partition is fitted into the casing and separates the hollowed out portion from a central passage through the cooling device, so that, as a cooling agent is forced into the hollowed out portion and out again, a heating agent may pass into the centrally arranged passageway of the device and intothe keg towhich the device is attached. In this manner the cooled surface of the housing keeps in a cool condition the bushing of the bung hole and prevents any expansion thereof.

In order that the invention may be more fully understood, I have disclosed a preferred embodiment in the accompanying drawings, in which 1 indicates a keg or other receptacle having a bung hole into'which the bung bushing 2 is inserted. Into the bung bushing is fitted a housing 3 that is preferably beveled. at 4 in order to provide a tight fit between the same and the bushing. Passing centrally part way through the housing 3 is a passageway 5 which registers with a passageway 6 formed in a removable sleeve 7. The sleeve 7 may be beveled at 8 to form a tight fit between the housing 3 and the end of the sleeve, so as to positively prevent any of the cooling agent that has been forced into the hollowed out portion 9 passing into the keg 1, or any of the heated pitch or other matter from keg 1 into the hollowed out portion 9. In order to properly secure the sleeve 7 in the passageway, the same is formed with preferably an enlarged head 10 that is threaded into an opening 11 of housmg 3. out portion 9 and, together with the same, forms a chamber through which a cooling agent may circulate.

In operation the cooling agent, as for instance, water, is forced in through the passageway 12 and, after the same has passed around the cylinder 7, and at the same time cools the housing 3, it is permitted to pass out the passageway 13. After the housing 3 has been inserted into the keg or other receptacle, the same is turned until the bushing 2 and cooling device inserted therein is at substantially the lowest point, so that any matter in the keg may run out. Hot air or steam is then forced into the keg through passageways 5 and 6, until the pitch in the keg 1 is melted and all of the same has run out. During the heating of the interior of the keg, the cooling medium, as water, is continuously passed through the housing 3 in order to maintain the bushing 2 in a cooled condition, so as to prevent any expansion thereof and any stretching or enlargement of the bung hole. After all the pitch or other matter lining the keg has been removed, the pipe or other means for forcing the heated medium into the keg, is removed, and new pitch or other matter is forced through passageways 5 and 6 into the keg until the same is properly coated. During the coating of the keg, as well as during the removal of the pitch therefrom, the cooling agent is passed through the housing 3 so that,

under no circumstances, will the bung bush ing 2 be permitted to expand. In this way the bung bushing is positively prevented from any movement and consequently from causing any leakage.

What I claim is:

1. In a device of the character described, the combination with a receptacle having a bung bushing, of a housing fitting into said bung bushing formed with a beveledextension, said extension being arranged with its end in the same plane as the end of the Opening 11 merges into the hollowed bushing in order to permit any matter contained in the barrel to pass out, said housing being formed with a hollowed-out portion, and a passage-way, and a sleeve secured to said housing, said sleeve being formed with a passage-way of the same size as said firstmentioned passage-way and in alinement therewith for presenting a continuous passage-way entirely through said housing, said passage-way being adapted to permit the insertion and removal of matter from said receptacle, and said hollowed-out portion being adapted to accommodate a cooling medium for the entire length of said housing.

2. In a device of the character described, the combination with a receptacle having a bung bushing, a housing formed with an extension fitting into said bung bushing, a hollowed-out portion and a passage-way extending partially through said housing, and a hollow sleeve threaded into said housing and having the hollow part thereof registering with said passage-way in said housing for providing an uninterrupted passage-way from the interior of said receptacle to the exterior, said hollowed-out portion of said housing being adapted to accommodate a cooling medium, and said sleeve being adapted to prevent the cooling medium from entering said receptacle.

In testimony whereof I afiix my signature in presence of two witnesses.
